The HCPL-315X consists of an LED optically coupledto an integrated circuit with a power output stage. Thisoptocoupler is ideally suited for driving power IGBTs andMOSFETs used in motor control inverter applications.The high operating voltage range of the output stageprovides the drive voltages required by gate controlleddevices. The voltage and current supplied by this optocouplermakes it ideally suited for directly driving IGBTswith ratings up to 1200 V/50 A. For IGBTs with higher ratings,the HCPL-3150/315J can be used to drive a discretepower stage which drives the IGBT gate.
